PAPER SLITTING AND WINDING MACHINE.

Specification of Letters Patent.

rammed Dee.17,1912.

Application filed December 29, 1911. Serial No. 668,443.

To all whom it may concern:

Be it known that I, Pozvrvs Hnimnnne, manufacturer. of 1 Tottenlmm Court road, London, England, have invented certain new and useful improvements Relating to Paper Slitting and lVinding -Machines, of which the following is a specification.

This invention relates to the production of a plurality of narrow strips from a single web of paper wound into coils or spools for the purpose of spinning into threads or the like. The width of the strips employed for this purpose is generally about it; of an inch.

In the production of narrow strips where they. have been wound adjacent to one another on a spindle dilliculty has been experienced and time wasted in separating the coils, and this ditliculty increased where attempts were made to wind longlengths in one coil. tThe productionof coils of greater lengththan 1400 yards resulted in great loss and waste owing to the coils beingdamag (1 when being separated and rendering them unfit for use in the spinning machine. There is an objection to the use of short coils as much time is wasted in replenishing the spinning machine with new coils. 1V here coils have been wound upon a number of spindles to avoid the difficulties de scribed, other difficulties have arisen.

The object of the present lnvent on is to so wind the straps that coils or bobbins of greater length, say 4,000 yards can be conveniently wound so as to be ready for use.

According to this invention the machine for cutting paper into strips is provided with spindles having independent collars or bosses on which the strips are wound, said' collars or bosses being mounted on two or more spindles and disposed in pivoted frames. The collars or bosses may either be of a greater width than the strip to be wound or of a width equal to the strip, in

which latter case distance rings or pieces are provided between the adjacent bosses. The bosses are adapted to be clamped closely together upon the shaft by any desired means. When the strips are being woundin closely adjacent pairs upon a common boss, means are provided whereby the series of pairs are spaced apart from one armther.

purpose of adjusting the position of the roll v of paper.

Means for adjusting the guide roll 0 and tension. roll f are provided.

The bearings 23, 23 are adapted to be taken out of the arms 8., 9, 11 and 12 for the purpose of removing the spindles 1 1 and 16 upon which the strips of paper are wound.

In use the roll of paper to be cut into strips is placed on the spindle d, the Web of paper is passed over the guide roll 6 around the tension roll 1, between the cutting rolls h and is and over the drum 0. A short length of paper is then cut and alternate strips are pasted on to the bosses on the spindles 14 and 16. The paper 1s supported by the drum 0 between the interval of winding and slittingand as it is coiled into disks,

late the tension of the paper. Rotary motion is transmitted from the shaft Q) to the shafts 4 and 7 and from the shafts 4 and 7 to the shafts l4 and 16 and from the shafts 3' let and 16 to the drum by frictional contact of the disks of paper on the shafts 14c and 16 with the drum 0. 'Ihemotion is transmitted from the drum 0 to the groove roll by means of gear wheels 79 and m. As the coils of paper increase in diameter the arms 8 and 9, 1-1 and 12, move on their pivots, the weight of the paper and arms being sufficient for frictional drive. When the desired length of paper has been cut and wound into disks the spindles 14 and 16 are removed from the bearings 23, 23, and the bosses 18, 18 are slid off with the disks of rolled paper.

Instead of employing the intermediate roller against which the spools bear the said intermediate driven roller may be dispensed with, the spools or coils bearing direct against the grooved roller of the cutting device and further, when the intermediate roller is employed it may be made of such tary diameter as will permit of more than two spools carrying axles being wound at the same time.

WVhat I claim and desire to secure by Let ters Patent is In a machine for slitting a web of paper into narrow strips by cutting rolls and windingsame onto separate bosses into the form of disks, a drum disposed between the .two spindles carrying said bosses, on which drum the disks of paper rest and by which the paper is supported between the interval of slitting and winding, a grooved roll, ro-

motion being transmitted to the grooved roll by frictional contact of the disks of paper with the drum, and gearing between the drum and the groove .roll.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
